Because I’m in my very early 20s I missed out on the huge Java craze. Everything was Python when I started getting a more formal education and before then all my work was in C++. Knowing more languages would obviously look better on a CV but I mean if I would benefit in a practical sense? I have two friends who are long time Java devs. And recently another friend who generally works with legacy C++ based systems from the early 2000s late 90s period had to work on a bunch of stuff in Java. Java is clearly still in large scale use among older systems. So would it be likely that eventually I would need to work on Java systems myself when my job is mostly JavaScript currently?
I was choosing at the start of my career between C# and PHP, and I chose PHP. I love the simplicity of the language, as it does everything I need, and it’s very quick to prototype basic funcionality in no time.
It was less voluntary to use Perl, but they pay a lot, and it always ended in PHP anyway.
